my logo kinda broke due to the portals in the new version =( i was lucky and got one made by powershroomsattack that time, and I modified it to be more appealing. I think it will make it a lot bettter if you, when you use a logo made by somebody else, add some finishing touches to it.
i also made loads of logos for me but i made so much that i couldnt decide which one i wanted so i stuck with my original parody of the san diego comic con....so thats another tip don't have too many logos
